Days after Monsanto paid $4.6 million to oppose the labeling of genetically engineered food in Washington, fellow agribusiness DuPont Pioneer contributed $3.2 million, it reported Tuesday.
The campaign against Initiative 522, which would require labeling of GMOs at retail, has raised $11.1 million.
The campaign for I-522 has raised $3.5 million.
A similar measure lost last year in California, where labeling opponents spent $44 million, compared with $9 million spent by labeling supporters.
